The ceilings of the new and larger part of the palace are vaulted throughout, with each support terminating in a stone pendant, giving the impression of a continuous series of blind arcades running along each wall.

The regimented orthogonality of the exterior extends to the perimeter offices, which are edged by a series of arcades lined with redoak veneer.

Archetypal forms such as porches, arcades and conservatories animate external edges, while courtyards and atria bring light and air into deep plans.
